type of weft replenishing loom provided.

with shuttle changing mechanism for changing shuttles, and substitutinga new shuttle containing a full bobbin, for the active shuttlecontaining a substantially exhausted bobbin.

Our invention v"particularly relates to improvements in the shuttlechanging mechanism of looms of the type referred to, and

-more particularly to improvements in the type of loom shown anddescribed in U. S. Letters Patent, No. 614,369, dated November 15, 1898.

In our improvements, a shuttle holder or magazine is provided, in whichare placed a number of shuttles, to be fed or carried,when required, ina shuttle holder, which is held in its forward inoperative position,until the substantial exhaustion of filling in the active shuttle isindicated by the feeler at the opposite end of the loom, when theshuttle changing mechanism is called into operation, on the next forwardmovement of the lay, and the shuttle box, mounted on the lay 4andcontaining the active shuttle with the substantially exhausted bobbintherein, is raisedto its upper inoperative position, allowingthe shuttleholder, with a fresh shuttle and a' full bobbin, to be brought intoalinement with the race-way, and said shuttle picked through the-shed inthe usual and spare shuttle holder, as it assumes the position of theshifting-shuttle box raised above it, when the spare shuttle is firstpicked across the lay.

Our invention consists in certain novel features of construction of ourimprovements as will be hereinafter fully described.

We have shown in the drawings portions of a loom of the type referredto, and patented in U. S. Letters Patent No. 614,369,

above referred to, with our improved shuttle changing mechanism combinedtherewith, sufficient to enable those skilled in the art to understandtheAconstruction and operation thereof.

which lever is loosely mounted ona stud 45', secured in'a stand 45 by 'aset screw a 45. The stand 45 is secured stand'46,fa'st to the loom side.

Loosely mounted on the stud 45 is aseo to .the main 'ond 1ever;47 seeFig. 1, which lever is held .in its outward position by a torsion spring48, which has one end secured to the hub,

47 on the lever 47, and the other end to a collar 49, secured, by'a setscrew 49 on the stud 45. Loosely mounted on the stud 4 -securedinaprojection 4 on the lever 47,

is a latch lever 50, which lever is held in its 'outward position by acompression spring 51, see Fig. 1. On an arm 50', forming a part of thelatch 50, is secured one end of a giveway or tension spring 52, theother end of said spring 52 is secured toone end of a connecting rod 53,the other end of the connecting rod 53 is pivotally attachedy to thelever 54, which lever is securedby a set screw 54 to a rod 55, operatedby a feeler, not shown.

Secured by a set screw 56 in the hub 46 on the stand 46, is a stud 56,see`Fig. 9,

which stud has looselyl mounted thereon a sleeve 57, which has securedto its inner end, by keys 58', a cam 58, which has openings 58" therein.The outer end of the sleeve 57 forms a flange 57'.

Loosely mounted onthe sleeve 57'is a mutilated pinion 59, which hasprojections 59. The pinion 59 has secured thereto a vlocking cam 60,which forms part of an outer sleeve 61, having a grooved surface 61'therein, in vwhich surface is guided a roll 62, loosely mounted on aStud 62' fast on the lever 47.

Upon the indication of the filling detector or feeler, not shown, thelever 54 is moved to its outer position, causing the latch through theconnector 53 and spring 52, to lock the lever 47 to the lever 44, seeFig. 2, so that the lever 47 will be moved to its inner position as thelever 44 is moved to its the roll 63, loosely mounted on a stud 63 on alever 64, which lever is pivotally mounted on a stud 64' secured on thestand 46. The lever 64 has secured in its upper part a stud 65, on whichis loosely mounted one end of a rod 65, which rod connects with andunlocks the locking lever 34 turning `its open slot toward the track 72on the lay when in its forward position, see Fig. 2. 66 is an adjustableplate, held in posltion on the flange 57', by boltls 66'; said plate 66has secured thereon a stud 66", on which is loosely mounted one end ofia link 67; the other end of the link 67 is connected by a stud 67' to apart 68 of agiveway lever 68. The hubs on the giveway lever 68 areloosely mounted on the stud y.69, see Fig. 8, secured on the stand 46.The other part 68" of the givewaylever 68 has fast theretoan adjustablepiece 70, having secured thereon a stud 70', on which is loosely mountedone end of a link 71. The other end ofthe link 71. is connected to a pin29"', secured in the sliding portion 29" of the lifterbar 29.

During the half revolution of the pinion 59, above referred to, theouter end 68" of the giveway lever 68 is given a lifting motion, causingthe shuttle box 25 to be raised to its upper position, and at the sametime causing the roll 35 to pass out of the slot of the locking lever 34and to follow the adjustable track 72", secured to the guide stand 72,turning the upright bar 22 on the stud 31", thereby bringing the shuttleholder 23 in alinement with the lay, lso that the shuttle 4' may bepicked through'the shed on the backward movement of the lay.

The shuttle box, and spare shuttle holder are constructed substantiallyas shown and described in U. S. Letters Patent No. 614,369, abovereferred to, having open slotted bottom plates for the picker stick topass into, and the shuttle box is opened at the back for the dischargeof the shuttle, when raised into its inoperative position.

There is also fixed on the lay the upright wall 28", in alinement withthe front of the reed, and above the race plate of the lay, said wall28" acts as a back for the shuttle box 25, to retain a shuttle in thebox and guide its passage across the lay, when the box is in itsoperative position on the lay, all as substantially described in saidpatent, No. 614,369.

The shuttle box 25, Fig. 2, is shown in its inoperative position abovethe upright wall 28", over which the shuttle has been discharged uponthe receiving platform 81, and the spare shuttle holder 23 is shownraised in its operative position on the lay. rIhe upright Wall 28 servesas a back for the shuttle holder, to guide the shuttle when pickedacross the lay.

A' tension spring 73 has one end secured to an-arm 29a of the lifter bar29, and its other end secured to an arm31a on the foot 31, and is usedto return the shuttle holder 23 to its inoperative position.

74 is a tension spring attached at one end to a stand 75, fast to theloom side, and at its other end to a stud 75', see Fig. 8, on a part 68"of the giveway lever 68. Loosely mounted on the stud 64 are the hubs 76'and 7 7 of the levers 76 and 77, forming the giveway lever.

78 is a compression spring encircling a stud 78', and acts to hold thetwo levers 76 and 77 together. rlhe levers 76 and 77 are operated by astud 7 9, secured in the inner part 68b of the giveway lever 68, andinserted between the levers 76 and 77, see

Fig. 8.

Secured in the outer end of the lever 77 is a stud 77", upon which isloosely mounted one end of the connector 80, which has its other endadjustably secured in a rod head 80', loosely mounted on a stud 81',secured to the receiving platform 81, which platform is pivotallymounted on the rod 82 on the stand82 fast to the loom side 1, and, holdsthe receptacle 83 for the substantially exhausted shuttles, The lever 77is moved to its downward position, through the operation of the givewaylever 68, thereby placing the lever 81 in its normal position to receivethe shuttles, see Fig. 2. These operations are performed on the backwardmovement of the lay, and on the forward movement of the lay the pinion"59 is given another half revolution, thereby completing the operation,and returning the parts to their normal position.

A protector rod 84, see Figs. 11,'and 12, is mounted ina hub 85 on thestand 85 secured to the lay. Secured to the outer end of the protectorrod 84, by set screws 86, is the hub 87 of a stand 87. Pivotally mountedon a stud 87 on the upper part of said stand 87, is a shuttle binderfinger 88 which has at its lower end an outwardly extending portion 88.The finger 88 is held in its upright position, as shown in Fig. 11, by acompression spring 89, bearing at one end against the finger 88, andhaving its other end extend in a recess in the stand 87.

A stand 90, having an upright portion 90', is secured to the lifter bar29, and when the shuttle box is raised to eject the shuttle, as shown-in Fig. 12, the upright portion 90 of the stand 90, moves the finger88, against the action of the -compression spring 89; by this operationthe filling thread from the shuttle, having its free end held in a clamp91 mounted on the breast beam 1, see Fig. 3, is allowed to pass freelyover the finger 88, and into the fabric being woven, the end of thefilling thread being severed adjacent the selvage of the fabric, andleaving the end attached to the clamp 91.

A torsion spring 92 encireles the. protector rod 84, and has one endsecured to the boss 93 on the stand 93, and its other end secured to acollar 94 on the rod 84 by a set screw 94'. Y The spring 92 acts to holdthe upper end of the finger 88 in engagement with the shuttle binder 25,and also to turn the protector rod 84 to its normal position, after ithas had a partial rotation.

The operation of our improvements is briefly as follows When the lay ismoving backward, after the detection of the near exhaustion of fillingin the active shuttle, the actuating lever 44 being in its outwardposition, as shown in Fig.l 9, the latch y50, carried on the lever 47,engages `with the lever 44, as shown in Fig. 2, and as the lay reachesits backward position, 'the pinion 59 is\ moved by the lever 47 intoposition to be engaged by the driving gear 41, and turned shuttle box25, and the spare shuttle holder 23, raising the shifting shuttle box 25to an inoperativeposition, and the spare shuttle holder 23 toanoperative position on the lay, at which time the lay has moved partlybackward, and the picking of the spare shuttle across the lay occurs asthe lay reaches its backward movement, at which time also the exhaustedshuttle in the shifting shuttle box 25, which is raised above thestationary wall 23, is discharged by itsmomentum upon the receivingplatform 81, see Fig. 2, and is arrested by the fixed shoulders 83on thereceptacle 83, which shoulders act to aline the shuttle with thereceptacle, and then the shuttle is raised above the shoulders 83 on thereceiving platform 81, through the kconnecting rod 80 by the lever 77,which is operated by themovement of the lever 68 as it is moved .up anddown, and the shuttle slides down the inclined surface of thereceptacle` 93 to its lower end where it may be removed or discharged.

When the levers 44 and 47 are engaged by the latch 50, and have beenmoved into operative position by the grooved cam surface 43 which camsurface is shown in Fig. 9, they are held in locked position by theguide 50a, above the latch 50, until said grooved cam has made acomplete revolution, and movedsaid levers outward with the latch 50,from under the uide 50, and permits the unlocking of sai levers.gagement of the levers 44 and 47, and while the shuttle has been pickedto the opposite end of the lay, and as the lay is movin forward again,the other lobe on the mutilated gear 41, engages and turns ythe pinion59 another one-half turn, moving the crank pin 66" to its upper' normalposition, and rea turning the shifting shuttle box 25 and the spareshuttle-holder 23 to their normal positions, with the locking lever 34moving the spare shuttle holder 23 under the magazine, as the roll 63 onthe lever 64 passes into the depressionk in the cam surface 58, all ofwhich is performed during one revolution of the grooved c`am`43, andwhile the levers 44 and 47 are locked under the bar 50a. The

During this en-l one-half a revolution, carrying the crank giveway lever68 is adapted to release the 115 v66 downward during the next forwardcommences to turn, the cam surface 58, carried by the pinion y59, shownenlarged in Figs. 9 and 10, moves the lever 64 outward, and through theconnecting rod 65, swings the locking lever 34 from its normal positionin Fig. 1, to the position shown in Fig. 2, being a preliminarymovement, to bring the spare shuttle holder` 23 out from under themagazine, and the continued moveme t of the pinion 59, as the. layreaches its fo ward position turns the crank 66" downward, and raisesthe end of the giveway lever 68, lifting the rod 29, connected with theshifting shifting shuttle box from the movement of its actuating crank,if the shuttle should fail to be properly positioned in the shuttle box,whenever a change of shuttles is .about to take place.

The two ,parts of the levers 76 and 77 form a giveway lever for'movingthe receiving lever 81 to release said lever from its actuator, if adischarged shuttle is not properly landed on the platform.

When the spare shuttle holder 23 is moving out from under the magazine,Athe lower end of the lever 21 follows said holder, and moves theretaining fingers 13 out from under a series of shuttles 4 in themagazine 4, 130

at the same time moving inward immediately above the normal position ofthe spare shuttle holder 23, the finger 17, which receives with the endof the lever 21, and moves the finger 17 out from under the shuttle, andallows it to drop upon the spare shuttle holder 23, and at the same timemoves the fingers 13 under the shuttle above, and prevents it fromdropping.

It will be understood that the details of construction of ourimprovements may be varied if desired.
